Imine-based multicomponent polymerization: Concepts, structural diversity and applications

“…6B, Deng 2020). [54] Although aromatic amines are known to be detrimental to the U-4CR [49] and the use of aldehydes with acidic α protons can lead to aldol condensation, they obtained quite high molecular weights, up to 33 kg mol. The introduction of azobenzene moieties endowed the polymers with some photosensitivity and their properties (cloud point temperature, contact angles and particle sizes) could be tuned upon irradiation (at 365 nm).…”

“…The introduction of azobenzene moieties endowed the polymers with some photosensitivity and their properties (cloud point temperature, contact angles and particle sizes) could be tuned upon irradiation (at 365 nm). [54] Eventually, Chen et al developed some cationic redox-responsive polymers for intracellular protein delivery application. In this case, two different disulfide-containing dicarboxylic acids were This is the authors' version of the article published in Progress in Polymer Science.…”

Progress in Isocyanide‐Based Step‐Growth Polymerization

“…In 2020, Deng et al used glutaraldehyde, photosensitive 4-amido-azobenzene, tert-butyl isocyanide, and carboxyl end-capped polyethylene glycols as monomers to prepare temperature/photo dual sensitive polymers via U-4CP at room temperature. [35] Because of the thermosensitivity and photosensitivity of the polymer, the size of the resultant polymer particles could be controlled by different light radiation and temperatures, which holds great potential for applications in controlling the pore size of cross-linked films and the selective channeling of particles. They later changed the monomers to 1,4-bis-(3-aminopropyl) piperazine, bis-carboxyl end-capped polyethylene glycol, tert-butyl isocyanide, and aldehydes, and multifunctional polyamides with thermal sensitivity, biocompatibility, and antibacterial activity were obtained.…”

Covalent organic frameworks and multicomponent reactions: an endearing give-and-take relationship

“…38 Another example is the deployment of MCRs in material chemistry and nanotechnology wherein a multitude of functionalized materials have been achieved. 39 These synthetic materials displayed diverse applications ranging from drug/gene delivery, 40 catalysis 41 and biosensing 42 to water treatment 43 and enzyme immobilization. 44 Further, in very many instances, MCRs are used in pharmaceutics as a straightforward synthetic route for the synthesis of important and vital drugs.…”
